Term
 Population geography
Definition
 Division of human geography concerned with distribution, composition, growth, and movement of populations
Term
 Demography
Definition
 The scientific study of population
Term
 Rates
Definition
 Record the frequency of occurrence of an event during a given time frame for a designated population.
Term
 Cohort
Definition
 A population group with a shared characteristic
Term
 Crude birth rate (CBR)
Definition
 live births / population x 1,000 (crude)
Term
 Total fertility rate (TFR)
Definition
 The average number of children that would be born to each woman if during her childbearing years she bore children at the current year's rate for women that age.
Term
 Crude d.eath rate (CDR)/mortality rate
Definition
 A mortality index usually calculated as the number of d.eaths per year per 1000 population.
Term
 replacement level
Definition
 The number of children per woman that will supply just enough births to replace parents and compensate for early d.eaths, with no allowance for migration effects, usually calculated at between 2.1 and 2.5 children.
Term
 Zero population growth (ZPG)
Definition
 Population in equilibrium, stable. (plus immigration)
Term
 Population pyramid
Definition
 A bar graph in pyramid form showing the age and composition of a population, usually a national one.
Term
 Dependency ratio
Definition
 number of dependents / population(wage earners) x 100
Term
 Rate of natural increase
Definition
 Birth rate minus the d.eath rate(cbr - cdr)
Term
 Doubling time
Definition
 The time period for any beginning total experiencing a compounding growth to double in size.
Term
 J-curve
Definition
 A curve shaped like the letter J depicting exponential or geometric growth. (1, 2, 4, 8, 16...etc)
Term
 Demographic transition
Definition
 A m.odel of the effect of economic development on population growth. A first state involves stable numbers with both high birth rates and rates, the second displays high birth rates, falling rates, and population increases. Stage 3 shows reduction in population growth as birth rates decline to the level of rates. The fourth and final stage again implies a population stable in size but with larger numbers than at the start of the transition process. An idealized summary of population history of industrializing Europe, its application to newly developing countries is questioned.
Term
 Demographic equation
Definition
 A mathematical expression that summarizes the contribution of different demographic processes to the population change of a given area during a specified time period. SEE OTHER CARD.
Term
 Ecumene
Definition
 That part of the earth's surface physically suitable for permanent human settlement; the permanently inhabited areas of the earth.
Term
 Nonecumene/anecumene
Definition
 That portion of the earth's surface that is uninhabited or only temporarily/intermittently inhabited.
Term
 Crude density/arithmetic density
Definition
 The number of people per unit area of land.
Term
 Physiological density
Definition
 The number of persons per unit area of cultivable land.
Term
 Agricultural density
Definition
 The number of rural residents per unit of agriculturally productive land
Term
 Overpopulation
Definition
 A value judgment that the resources of an area are insufficient to sustain adequately its present population numbers.
Term
 Carrying capacity
Definition
 The maximum population that an area can support on a continuing basis without experiencing unacceptable deterioration. For humans, the numbers supported by an area's known and used resources-usually agricultural ones.
Term
 Population projections
Definition
 A statement of a population's future size, age, and s.ex composition based on the application of stated assumptions to current data.
Term
 Thomas Robert Malthus
Definition
 English economist, demographer, and cleric who suggested that unless self-control, war, or natural disaster checks population, it will inevitably increase faster than will the food supplies needed to sustain it.
Term
 S-curve
Definition
 Leveling of an exponential/J-curve.
Term
 Homeostatic plateau
Definition
 relatively stable state of equilibrium, to the balance between population numbers and resources. (carrying capacity)
Term
 Neo-Malthusianism
Definition
 The advocacy of population control programs to preserve and improve general national prosperity and well-being.
Term
 Population/demographic momentum
Definition
 The tendency for population growth to continue despite family planning programs because of a relatively high concentration of people in the childbearing years.
Term
 Demographic equation (specific m.odel)
Definition
 P2 = p1 + B1-2 - D1-2 + IM1-2 - OM1-2, where P2 is population at time 2, p1 is population at beginning date, B1-2 is the number of births between times 1 and 2, D1-2 is the number of d.eaths during that period, IM1-2 is the number of in-migrants, and OM1-2 is the number of out-migrants between times 1 and 2.
Term
 Population density
Definition
 A measurement of the number of persons per unit area of land within predetermined limits, usually political or census boundaries.
